What is "chickon express"？a“fast food place from USA,... who knows that?

这个应该是鸡的一种，做成熟食的叫法。
请参考：
Chickon：
1. A chicken purchased from a butcher that has unusually long legs and dry yellow skin. Basically, a chickon is the exact opposite of what you'd look for when selecting a tasty chicken from a butcher. It is usually what is left of the fresh chicken at the end of the day because no one has purchased it.

The term originates in the Caribbean from the late musical legend Bob Marley. The term is properly pronounced as "Chik-kahn"

2. A chick who is unattractive, but is still bangable. She's the girl who you'd only call up if you had no one else to meet up with for a good shag.

chickon 你输入有问题 好像是chicken 因为你说的是和快餐有关系 并且你那错的那个我根本翻译不了 我刚查了资料 那个单词根本不存在 . 谁知道什么是属于美国的快餐，例如小鸡只类的. 请问是要我帮你翻译还是回答.

什么是“小鸡快递”？一个美国的快餐店...有谁知道吗？
